s claims. (C1. 24o-10s) This invention relates toy improvements in lampshade holders.

The main objects of this invention are:

First, to provide an improved lamp shade which is capable of readyadaptation to lamps of the type including a lamp socket having anexternally threaded portion and which engages the lamp socket in a verysecure and effective manner for supporting the shade in the desiredposition and against tilting movement.

Second, to provide a lamp shade which, while scription to follow. Theinvention is defined in' the claims.

A structure which embodies the features of my invention is clearlyillustrated in the accompanying drawing, in which:

Fig. 1 is a fragmentary side elevation of a lamp embodying the featuresof my invention, portions being broken away and partially in section online I-I of Fig. 2 to show structural details.

Fig. 2 is an inverted view of the lamp shade and holder partially inhorizontal section and partially broken away.`

Fig. 3 is an enlarged fragmentary view in vertical section illustratingdetails of the shade structure.

In the embodiment of my invention illustrated I represents a lampstandard which is provided with a socket 2 having an externally threadedportion 3. The lamp bulb 4 is threaded into the socket. The threads 3commonly result from the forming of the internal threads to receive thelamp. The shade holder element 5 is provided with a central hub portion6, a rim portion 'I and spider arms 8 connecting the rim portion to thehub portion. The hub portion has a central opening 9 therein of suchdiameter as to receive the socket of the lamp.

The shade holder 5 is of substantial thickness and is preferably formedof iireproof or fire resistant material, the product commonly known asMasonite being an example of material which I have found satisfactory.The holder is rotatively forced down on the socket with the result thatthe threads of the socket form threads in the holder opening and a verysecure engagement results, one which prevents accidental disengagementand also tilting of the holder on the socket. Y Y

The rim 'I is provided with a spaced series of curved recesses ornotches Ill adapted to receive the inwardly disposed utings II of thefluted shade I2. These flutings and recesses are preferably so formedthat the flutings fit the recesses, thereby preventing shifting movementof the shade on the holder. The inwardly disposed flutings of the shadehave pairs of eyelets I3 formed therein adapted to receive theribbon-like strand I4 which is arranged through the eyelets and lbelowthe segmental portions I5 of the rim between the recesses. Thiseffectively retains the shade on the holder and the ribbon or strand maybe tightened up so as to clamp the shade on the holder, thus providing avery secure assembly and one in which the shade holder cannot be tiltedon the lamp socket or the shade tilted or shifted on the holder withoutit being subject to distorting stresses.

The shade walls terminate in a cylindrical top portion I`6 which has areinforcing sleeve I 'I secured within the same. The rufe or otherornamental material I8 is secured around this cylindrical portion andthe shade illustrated is provided with a ruled trimming I9 at its loweredge.

The shades and the holders may be packed and shipped in the knockdownand readily assembled by the merchant or the user.

I have illustrated and described an embodiment of the invention which Iconsider very practical. I have not attempted to illustrate otherembodiments or adaptations which I consider desirable, particularly inmatters affecting design, as it is believed this disclosure will enablethose skilled in the art to embody `0r adapt my invention as may bedesired.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

l. The combination of a lamp shade holder of substantially fiat brousmaterial comprising a central hub portion, a rim portion and a spiderportion connecting said hub and rim portion, said hub, rim and spiderportions all lying substantially in a plane, said hub portion having acentral opening therein adapted to receive a lamp socket having an`externally threaded portion and for threading engagement therewith, thefibrous material of said hub portion being of substantial thickness topermit of a substantial engagement of said hub portion over said lampsocket, the rim portion having a plurality of spaced recesses therein, ashade having fiuted side walls, the flutings being disposed in saidrecesses for supporting engagement with said holder, said shade slopingupwardly and inwardly from said rim portion, said shade having openingsin its utes engaged in said recesses and positioned below the Ashadeholder, and a strand threaded through said openings and engaging theVlower side of the pori tions of the holder rim portion between therecesses thereof to retain the shade on the holder. f 2. Thecombi-nation of `a lampgfshade holder of substantially ziat fibrousmaterial comprising a central hub portion, a rim portion and a spiderporting engagement with said holder, said shade sloping upwardly andinwardly from said rim portion, said shade having pairs of eyelets inits iiutes engaged in said recesses and positioned bel low the shadeholder, and a strand threaded` through said eyelets and engaging thelower side of the segmental portions of the holder rim portion betweenthe recesses thereof torretain the shade on the holder. s'

3. .The V'combination of a :lamp shade holder l including a rim portionhaving a plurality of portion connecting said hub portion and 'ingfa'pluralitylof uniformly' spaced fcurvedrei cesses therein, a shadehaving fluted side walls, the Vutings fitting :into said recesses for.Sup-

15 holdensaid shade sloping upwardly and inwardly Y spaced recessestherein, a shade having uted side walls, the utings being disposed insaid recesses for supporting engagement with said froml saidrimgportion, said shade having openings in its ilutes, said openingsbeing positioned Aadjacent andbelow the lower side of the shade holder,and a strand threaded through said openings and engaging the lower sideof the portions of the holder vrim portion between the recesses thereofto retain the shade on the holder.
